[Relevance of treatment compliance in heart failure].

It is recognized that the irregularity in therapeutic compliance is one of the main unstabilizing factors leading to hospitalization in patients with heart failure (HF). In this review, we specifically deal with the Pharmacological Therapeutic Adherence (PTA) in HF patients, and especially with the adherence problems related to those drugs which have been shown to improve the prognosis of the disease. The impact of a deficient PTA (DPTA) jeopardizes the efficiency of the new neurohormonal inhibitor drugs which have proven benefit in wide and expensive clinical trials.
